LANTERN GLOBE.

Application filed March 21, 1923. Serial No. 626,558.

To all 107mm it may concern:

Be it known that I, CHARLES EnlVHALIN,

a citizen of the United States, residing at Salt Lake City, in thecounty of Salt Lake and State of Utah, have invented certain new anduseful Improvements in Lantern Globes, of which the following is aspecification.

My invention relates to lanterns, and has for its object to provide aglobe for an electriclantern which is made of a plurality ofplano-convex lenses integral at their edges with the contiguous lensesand preferably with the convex surfaces meeting'in regular curves togive the globe a spherical shape, except on one face Where the glass isex tended and externally threaded for fasten ing the globe in thelantern.

These objects I accomplish with the device illustrated in theaccompanying drawings in which similar letters and numerals indicatelike parts throughout the several views and described in thespecification forming a part of this application and pointed out in theappended claim.

In the drawings in which I have shown a substantial embodiment of myinvention,

Figure 1 is an elevation of an electric lantern with one of my globes111 place thereon. Figure 2 is tSlClQ' elevation of the globe in detailwith some of the plane surfaces shown in dotted lines. Figure 3 is asection of the globe on line 33 of Figure 2. Figure 4 is a section online -ls of Figure 2.

I have shown and I use a common form of electric lantern A having a bailB, a battery container 0 and a base frame I), which base frame is madeof small wires to support the lantern and yet obstruct the rays of lightas little as may be while they support the lantern and protect the globefrom being broken. in electric bulb E is screwed into tl e bottom of thebattery container 0 and the commonly used switch is mounted in the sideofsaid container C to open and close the electric circuit of said bulbE, as

desired. In the bottom of the said battery container I provide aninternally threaded socket within which is screwed the neck of the globeG. The said globe G is made of lens glass and consists of a plurality ofplano-convex'lenses, the lower one preferably positioned parallel withthe base D of the lantern. In the globe shown in the drawings I haveillustrated a globe having a cubiform interior, but other shapedinteriors, such as a dodecahedral or an octagonal form may be used,thereby increasing the number of lenses and multiplying the focalpoints. With the cubiform interior I provide five lano-convex lenses,one at the one central bulb E. By increasing the number of planesurfaces on the interior of the globe G the number of focal points willbe increased, should that be desired, and the number of bulls eyesmultiplied.

Having thus described my invention I de-' sire to secure by LettersPatent and claim A lantern comprising a frame in which a globeis mountedand an electric light bulb as its source of illumination; said globefastened in the bottom of said frame and surrounding said electric lightbulb in spaced relation thereto, said globe consisting of live planoconvex integral lenses one forming thelgiettom of said globe and theother four the sides of said globe integrally formed as a sphere exceptat the side nearest the frame, which side is extended and externallythreaded for engagement with said frame.

In testimony whereof I have afiixed my signature.

CHARLES E. WHALIN.
